18 years as a full-time composer and at last my first US commission!

HRT stands for High Rise Terminal, a term from linguistics which refers to the way that some English speakers (especially Australians, sometimes Americans) end their sentences with a rising inflection, sometimes giving a statement the feel of a question.

Self-evidently, a recurring melodic motif of HRT is a schematised reflection of this inflection.
